In order to achieve this result, it utilizes frameworks and javaScript language libraries such as React.js, Vue.js and Angular, an additional manifest file (defines mobile and desktop web browser features, such as upper toolbar color and page icon) and Service Worker technology (which enables the app to operate in the background and without access to the Internet).

Compliance with PWA is verified by checking items on the so-called PWA Checklist and running a Google Lighthouse benchmark.

Advantages offered by PWA

A PWA combines the best elements of the web browsing experience offered by web browsers and applications.

Like a web browser, it allows easy and direct access to a search engine and does not require any additional installations. Like an application, it allows use of native functions of a mobile device (push notifications, camera, QR codes/barcodes, geolocation) to improve user experience.

Business applications

PWAs address real business needs:

entry into new markets, operation on markets where Internet access is limited (e.g. the Nigerian e-commerce app – Konga)

desire to acquire new users; the need to download a new app is a barrier for many users – PWAs are generally available not unlike any other website
